To all whom, it may concern:

Be it known that 1, LoN BoNNEnoI, of Troyes, France, have invented a newand useful Improvement in Wrapping- Machines, which improvement is fullyset forth in the following specification.

This invention has for its object a machine for wrapping pastils orcakes of chocolate or other objects, whether round or otherwise, intin-foil or paper. The machine shown inthe drawings is speciallyintended for wrapping round pastils or cakes in tin-foil.

In the drawings, Figure 1 is a plan of the machine. Fig. 2 is alongitudinal section through the center of the machine. Figs. 3 to G arepartial sections for showing the position of the dierent parts atdifferent moments and for elucidating the action of the machine. Fig. 7is a detail View.

a a are the pastils or cakes, and b the sheet of tin-foil in which thecake is wrapped.

The frame of the machine is formed of a foundation-plate 1, providedwith four pillars 2, 3, 4, and 5. The pillars support a table 6, whichcarries a plate 7. 8 is a vertical shaft, upon which the controllingparts of the machine are mounted. The shaft carries a bevelwheel 9,actuated by a pinion 10, which is keyed to the crank-shaft 11. Threecams, the function of which will be later explained, are keyed upon theshaft 8. Upon the plate 7 a box 12 is fixed, which contains the pastilsor cakes a to be wrapped up in tin-foil. They are placed in the box byany suitable means..

Figs. 1 and 2 show the parts in the position in which they are at'themoment the wrapping operation is about to commence.

The first pastil or cake of the pile, commencing from the bottom, islodged, as shown in Fig. 2 in a recess in a movable piece 13, whichslides under the box and which will hereinafter be called the carrier.7The carrier 13 slides between the guides 14 and 15, placed upon theplate 7. When the crank is turned, the cam 16 acts upon the roller 17and causes the carrier 13 to advance into the position shown in Fig. 3,and the slide 18 is at the same time moved beneath the carrier by thereturning-springs 19 and 2O in such a man ner that t-he cavity 21 in theslide coincides with the hole 22 in the carrier and with oriflee 23 inthe plate 7.

Care is taken to ar- .the spring 31, which in what manner the same isthe slide 18, above the cavity 21, a sheet h of tin-foil for wrappingthe pastil or cake up in. As will be seen, the slide 18 is provided withflanges 24 and 25 in orderto support the sheet of foil in position. Theslide is formed of two plates, one above and the other below the table6. The two plates forming the slide are held together by bolts, whichslide in the grooves 26 and 27 in the table 6. The pastil or cake afalls, pushing before it the sheet of foil b. 28 is a plunger, which bythe effect of the cam 29 actuating the lever 30 then takes the positionshown in Fig. 4. The plunger 28 is then raised by bears against theabutment 32, which is integral with the box 12. The abutment acts alsoas abearing or guide to the stem of the plunger. The pastil or cake anow rests in the orifice 33 of the table upon the lower portion of theslide. The slide 18 is moved into the position shown in Fig. 5, and inits travel folds the left-hand side of the sheet b over the pastil orcake a. The slide then comes, by the action of the cam 34, back into itsfirst position, (shown in Fig. 2,) and in its travel folds the righthandside of the sheet l) (see Fig. 6) over the pastil or cake. The cavity35, formed ip the lower portion of the slide, coincides with the orifice33 in the table, thus allowing the pastil to fall. At this moment theWrapping is complete.. At the moment at which the slide 18 commences toreturn to its first position the carrier 13 is moved back to itsoriginal position b v the returning-springs 36 37 and is ready toreceive a new pastil.

Of course the present invention is not limited to the means foractuating the parts, which may be altered as desired.

Having now particularly described and ascertained the nature of` my saidinvention and to be performed, I declare that what I claim is-y 1. lu awrapping-machine, a series of horizontal reciprocating plates providedwith apertures adapted to receive the wrapper and the article to bewrapped, said plates arranged to slide one above the other in such amanner that the apertures therein will be successively brought into andout of register, thus folding the wrapper about the article.
